Since it was put into operation in 1966, the medium and heavy plate production line has undergone many large-scale technical transformation. In 1998, the finishing mill and straightener were transformed. In 2011, the heating furnace, roughing mill, cooling bed and bilateral shear were transformed. At present, there are two production units - steel rolling finishing line and heat treatment line.It has been out of production since April 2017.
